Embodiment 1

[0034] This embodiment provides a kind of detection method of octyl methoxycinnamate in textiles, comprising the following steps:

[0035] The first step is to take a sample from the textile: use stainless steel scissors to cut the sample into small rectangular pieces with a diagonal length not greater than 5mm.

[0036] In the second step, take 1.0 g of the shredded sample and place it in a 40 mL container (reaction tube in this embodiment), then add 10 mL of methanol to the container, place the container in an ultrasonic cleaner for ultrasonic extraction for 30 min, The ultrasonic frequency is 50kHz, and the ultrasonic temperature is 25°C to obtain the extract;

[0037] The third step is to filter the extract obtained in the second step to obtain the test solution, specifically, filter 1 mL of the extract with a 0.45 μm organic filter membrane into the sample bottle;

[0038] In the fourth step, the liquid to be tested obtained in the third step is analyzed by ultra-high pe...

Embodiment 2

[0055] This embodiment provides a kind of detection method of octyl methoxycinnamate in textiles, comprising the following steps:

[0056] The first step is to take a sample from the textile: use stainless steel scissors to cut the sample into small round pieces with a diameter not greater than 5mm.

[0057] In the second step, take 1.0 g of the shredded sample and place it in a 40 mL container (reaction tube in this embodiment), then add 8 mL of methanol to the container, place the container in an ultrasonic cleaner for ultrasonic extraction for 40 min, The ultrasonic frequency is 80kHz, and the ultrasonic temperature is 22°C to obtain the extract;

[0058] The third step is to filter the extract obtained in the second step to obtain the test solution, specifically, filter 1 mL of the extract with a 0.45 μm organic filter membrane into the sample bottle;

[0059] In the fourth step, the liquid to be tested obtained in the third step is analyzed by ultra-high performance liqu...

Embodiment 3

[0067] This embodiment provides a kind of detection method of octyl methoxycinnamate in textiles, comprising the following steps:

[0068] The first step is to take a sample from the textile: use stainless steel scissors to cut the sample into small elliptical pieces whose long axis is not greater than 5mm.

[0069] In the second step, take 1.0 g of the shredded sample and place it in a 40 mL container (reaction tube in this embodiment), then add 12 mL of methanol to the container, place the container in an ultrasonic cleaner for ultrasonic extraction for 20 min, The ultrasonic frequency is 40kHz, the ultrasonic temperature is 30°C, and the extract is obtained;

[0070] The third step is to filter the extract obtained in the second step to obtain the test solution, specifically, filter 1 mL of the extract with a 0.22 μm organic filter membrane into the sample bottle;

[0071] In the fourth step, the liquid to be tested obtained in the third step is analyzed by ultra-high perf...

Abstract

The invention belongs to the technical field of detection methods and in particular relates to a method for detecting iso-octyl p-methoxycinnamate in textiles. The method comprises the following steps: 1, sampling textiles; 2, weighing a certain amount of samples to be added into a container, adding methanol into the container, and performing ultrasonic extraction on the container in an ultrasoniccleaner for 10 minutes to an hour so as to obtain an extracting solution; 3, filtering the extracting solution obtained in the second step so as to obtain a to-be-detected solution; 4, analyzing theto-be-detected solution obtained in the third step by using an ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MSMS). Compared with the prior art, the method disclosed by the invention can simply, rapidly, accurately and reliably detect the content of the iso-octyl p-methoxycinnamate in textiles and meet detection requirements of the iso-octyl p-methoxycinnamate in Washington Child Product Safety Act.

Description

technical field [0001] The invention belongs to the technical field of detection methods, in particular to a detection method of octyl p-methoxycinnamate in textiles. Background technique [0002] Octyl p-methoxycinnamate is a commonly used sunscreen, anti-aging agent and UV absorber. According to relevant studies, octyl p-methoxycinnamate has mutagenic effects, teratogenic effects and developmental toxicity on the human body, and has potential chronic health effects. [0003] In the "Washington State Children's Product Safety Act" published by Washington State of the United States, octyl p-methoxycinnamate was listed as Chemical High Concern to Children (Children High Concern to Children, referred to as CHCC). The bill requires that children's products (including components and raw materials) placed in Washington State must be declared if they contain more than 5mg / kg of octyl p-methoxycinnamate. [0004] At present, there is no standard test method for the detection of o...
